It's very rare, but possible, for babies to be born with a tooth or two. It is also possible for infants to not get teeth until after they are a year old. Every child is different, and even if your little one IS teething, it can take a couple of months or more for it to actually break the surface. So sit back and hold on, it's a long ride. Try giving her different textures things to chew on, chilled teething rings or frozen damp washclothes, if she's having a really hard time you can give her Hyland's Teething Tablets (a homeopathic remedy that REALLY works) or baby tylenol. Motrin is not recommended for babies under 6 months due to possible bad reactions. Baby orajel is also not recommended as it doesn't last very long at all and it can numb the tongue, making it difficult to suck (especially troublesome for breastfeeding) or the throat, making it difficult to swallow.
